Morcemcolor^® Epoxi R2 T

Composition

Epoxy mortar of two antacid components, where the part A is constituted by a mixture of resin epoxy, inert siliceous and additives, and the part B is constituted by catalysts of  organic nature.

Features and applications

• Easy application and cleaning even in comparison with the cementitious grouts for tiles.
• Stable and uniform colour in all types of tiles.
• Resistant to UV rays exposure  and weather and climate action.
• High mechanical strength.
• Without absorption.
• It prevents the proliferation of moulds and fungus
• Total absence of cracks or fissures after the hardening.
• For antacid laying and filling in pavements and coverings, indoors and outdoors of ceramic tiles and glass mosaic with joints of 1 to 15 mm of width.
• Pavement joints with radiant heating.
• Foors and walls  bathrooms and showers
• Cooking hobs, terraces and balconies.
• Optimal chemical resistance, suitable for surfaces exposed to aggressive chemicals, such as: dairies, breweries, butchers and food industries in general, advised also for filling joints in swimming pools, including thermal and saline water.
• The product can be used for ceramic tiles stucco in environments submitted to direct contact with food, as kitchens, slaughter houses, meat counters , fishes, lacteal, pastry shops, etc
• Suitable for stucking and landfilling of mosaic joints also in swimming pools with MORCEMDRY system.

Substrates

• The adhesive or mortar used for the laying of ceramic pieces must be completely dry and hardened.
• The joints must be dry and clean in its entire length and depth, being empty at least 2/3 of the thickness of the ceramic piece.
• The adhesive or mortar remains  between joints must be eliminated

Instructions for use

• Cut the corner of the bag containing the component B and pour it  entirety on the component A (dough). Mixe relation of 100 parts by weight of component A for 8 parts by weight of component B (wear gloves).
• Mix the two components through agitation with  a drill with a spiral agitator until  to get a homogeneous mixure without lumps.
• Scratch with a spatula or trowel the walls and the bottom of the container mixture to avoid product residues without reacting.
• Partial mixtures mustn´t be realized.
• The obtained product from the mixture may work for approx. 1 hour at a temperature of 23° C.

• Refill the joints with a rubber trowel, it is necessary to compact the product firmly, applying it in diagonal sense of the joints and removing the excess of product with the same rubber trowel.
• The workability and hardening time of the product is greatly influenced by the ambient temperature, the ideal temperature application is between + 18° C to + 23° C. In these conditions the workability time will be 1 hour and the traffic will be possible after 24 hours, but if the temperature is + 15° C we will need three days to circulate.
• The pavement commissioning with chemical attacks is possible after 5 days at temperatures of + 23 ° C and after 10 days at temperatures of + 15 ° C.
• With temperatures between + 8° C and + 12° C the product is very consistent and difficult to apply and the hardening time is greatly extended. Please do not add water or solvents to improve its workability.
• At very high working temperatures, it is suitable to apply the product quickly in order to reduce the working time from the reaction heat of  that it can happen in the joints.

• The Cleaning and finishing will be done when the product would still be fresh and in the shortest possible time , taking care to not empty the joints and without leaving veils on the surface of the ceramic pieces.
• Spread manually,  clean water on the tiles surface , the first cleanliness using a trowel with a white wet felt, doing circular movements in hourly and anti-hourly sense, to seal perfectly the sides of the ceramic pieces and removing the excess of product that stays on the ceramic pieces. Later do it a second times with a rigid sponge (type sweepex) to obtain a joint with smooth and firm surface, removing totally the product of the ceramic pieces taking care to not empty the joint and drying the excess  water, to avoid  leaving residual veils on the ceramic pieces.
• When felt and sponge are impregnated of resin and the cleaning is no longer possible, they must be replaced.
• Another method of cleanliness is with a monobrush, once it has been taken the joint  excess of the ceramic surface,  spreads  water on the grouted surface and the cleanliness is done with a monobrush equipped with felt. Replace the felt disc when this one is impregnated with product.
• If there were any transparent veils on the ceramic surface, they can be eliminated after 24h or after the joint hardening (depending on the temperatures), using DESMOR EPOXI (consult its technical sheet for its correct use).

Cautions and recommendations

• Apply preferably the product with temperatures  between +18 ºC and +23ºC. Avoid to apply in low temperatures conditions  or high environmental dampness to avoid the superficial carbonation formation that might alter the color uniformity 
• Remove immediately the excessive parts of product of the ceramics surface because when it hardens, it will be only possible to remove it mechanically, with serious risks for the final  work result.
• Mix the two components (A + B) properly.
• Change frequently the wash water.
• Change frequently the felt and the sponge if they are impregnated with product.
• Do not tread on the newly applied surface to avoid staining the pavement with resin residues.
• The product can´t be applied on very porous pieces as for exemple. Fired clay or cement ground.
• Do not cover with fabrics or other materials recently applied to prevent the condensation formation that would result from the superficial carbonation product altering its uniformity color.Wait about 24-48 hours depending on the temperature before protecting the surface.
• In the case that the application is on natural stone, it is indispensable to do  a preliminary test to verify the possible absorption of epoxy resin on slabs. If it happens a darker veil on the surface and sides of slabs would appear and it couldn´t be removed. This problem occurs in general in clear color of marbles.
• The product cannot be used on surfaces where there are confined chemical aggressive substances admitted only for intermittent contact (see chemical resistance tables).
• Do not mix the product with water or solvents.
• With  ceramic tiles pressed by compaction and with a similar surface of  wood  it can be difficult to remove the spots. In this case , it is recommended to do a previously test or to consult to the technical department.
• Do not use the product for applications not listed in this technical data sheet.

Consumption according to dimensions (kg/m²)

* Consumption calculated for empty joint, without adhesive residue.
**For the calculation of consumption of any other format, use the following formula: (A+B)/(AxB) x C x D x
0,155 = kg/m2

Where:
A = Width of tile (cm)
B = Tile length (cm)
C = Thickness of the tile (mm)
D =Seam width (mm)

Packaging

Plastic container of 5 kg Bi-component on pallet of 450 kg. Storage up to 24 months in its original closed packing and without overturning, sheltered by the wheather and the dampness.
